CVE-2026-125709 1 Redhat 4 Enterprise Linux, Hummingbird, Openshift and 1 more 2026-11-10 4.2 Medium
A flaw was found in libstdc++. When a byte-by-byte write operation fails during file stream processing, the library may still append data into the internal memory buffer. An attacker capable of inducing repeated write failures in an affected service can trigger a buffer overflow, potentially resulting in a Denial of Service (DoS) or memory corruption.
CVE-2026-112323 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-10 7.5 High
The AUTH_GSSAPI handler in lib/rpc/svc_auth_gssapi.c in MIT Kerberos 5 (aka krb5) 1.5.2 and later allows remote attackers to cause a denial of service (memory exhaustion in kadmind) by sending repeated failed AUTH_GSSAPI_INIT requests. Each failed request allocates client state that is only freed after a 15-minute expiration timeout, allowing an attacker to accumulate memory faster than it is reclaimed.
CVE-2026-119079 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-10 7.5 High
decode_sequence_of() in lib/krb5/asn.1/asn1_encode.c in MIT Kerberos 5 (aka krb5) 1.11 and later grows the decoded element array one entry at a time, which allows remote attackers to cause a denial of service (CPU consumption in the KDC) by sending an unauthenticated AS-REQ or TGS-REQ with a large number of elements in a SEQUENCE OF field over TCP.
CVE-2026-112316 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-10 6.5 Medium
xdr_krb5_tl_data() in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) does not free partially decoded data on failure, which allows remote authenticated users to cause a denial of service (memory leak in kadmind) via crafted RPC requests that trigger a decode failure.
CVE-2026-92823 2 Red Hat, Redhat 7 Enterprise Linux, Enterprise Linux, Hardened Images and 4 more 2026-11-10 6.2 Medium
A flaw was found in libmodulemd. In builds with rpmio support enabled, compressed modulemd YAML is decompressed through a custom read handler that does not enforce a cumulative decompressed-size limit before parsing. An attacker who can supply a highly compressible compressed YAML file can cause excessive CPU and memory consumption, resulting in a denial of service.
CVE-2026-92822 2 Red Hat, Redhat 7 Enterprise Linux, Enterprise Linux, Hardened Images and 4 more 2026-11-10 6.2 Medium
A flaw was found in libmodulemd. When parsing module metadata, the xmd field is converted into nested GVariant values through recursive YAML mapping and sequence helpers without a recursion-depth or node-count limit. An attacker who can supply crafted modulemd YAML with deeply nested xmd content can cause stack exhaustion or excessive resource consumption, resulting in a denial of service.
CVE-2026-120749 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-10 6.2 Medium
A flaw was found in D-Bus. With a privileged Monitoring client attached (for example dbus-monitor or busctl monitor), an unprivileged local user can cause dbus-daemon to abort if a driver-originated broadcast such as NameOwnerChanged or ActivatableServicesChanged cannot be delivered to a recipient (for example due to a deny rule or an exceeded outgoing message queue). Driver broadcasts still use serial 0; when delivery fails, composing the monitor error reply asserts reply_serial != 0 and aborts the daemon.
CVE-2026-112318 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-09 6.5 Medium
The policy RPC stubs in kadmin/server/server_stubs.c in MIT Kerberos 5 (aka krb5) 1.5.3 and later do not reject a NULL policy name decoded by xdr_nullstring(), which allows remote authenticated users to cause a denial of service (kadmind crash via NULL pointer dereference) by sending a policy request with an empty policy name that reaches authorization checks or logging code.
CVE-2026-112321 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-09 7.5 High
The AUTH_GSSAPI handler in lib/rpc/svc_auth_gssapi.c in MIT Kerberos 5 (aka krb5) does not free decoded arguments on certain error paths, which allows remote attackers to cause a denial of service (memory exhaustion in kadmind) via crafted AUTH_GSSAPI_INIT requests that trigger authentication failures.
CVE-2026-122056 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-09 5.9 Medium
A flaw was found in OpenSCAP. A heap-based buffer overflow can occur when processing a specially crafted Extensible Configuration Checklist Description Format (XCCDF) document using the sds-compose option. An attacker could exploit this vulnerability to corrupt memory, resulting in an application crash and a Denial of Service (DoS).
CVE-2026-121995 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-09 7.5 High
A stack buffer overflow in the GDB client's tracepoint upload handler allows an attacker-controlled debug stub to corrupt stack memory automatically during connection setup. The overflow results from GDB reading beyond the current reply boundary into a stale prior reply in the shared packet buffer.
CVE-2026-123876 3 Containers, Red Hat, Redhat 7 Podman, Enterprise Linux, Enterprise Linux and 4 more 2026-11-09 4.4 Medium
A flaw was found in the default seccomp profile used by Podman via containers-common. Deny rules for AF_VSOCK and NETLINK_AUDIT compared socket arguments with unmasked 64-bit equality. Because the kernel truncates those int arguments to 32 bits, setting upper bits can bypass the deny rules.
CVE-2026-71226 2 Redhat, Smuellerdd 10 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 7 more 2026-11-09 7.3 High
Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers.
CVE-2026-115207 2 Red Hat, Redhat 5 Enterprise Linux, Enterprise Linux, Hardened Images and 2 more 2026-11-09 5.5 Medium
A flaw was found in GNU patch. An attacker can achieve arbitrary file creation outside the intended working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to missing validation during automatic patch reversal, absolute file paths in patch headers are accepted rather than rejected. Consequently, the utility can create files in arbitrary locations with the permissions of the executing user.
CVE-2026-101296 3 Apache, Apache Software Foundation, Redhat 4 Apache Tomcat, Tomcat, Tomcat and 1 more 2026-11-09 8.1 High
A missing critical step in authentication vulnerability in Apache Tomcat when the JNDI realm was configured with with a non GSSAPI SASL authentication mechanism allowed attackers to authenticate without providing the correct password. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.26, from 10.1.0-M1 through 10.1.60, from 9.0.0.M1 through 9.0.122. The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.27, 10.1.61 or 9.0.123, which fix the issue.
CVE-2026-88833 2 Busybox, Redhat 3 Busybox, Hummingbird, Rhel Els 2026-11-09 6.5 Medium
A flaw was found in BusyBox's udhcpc DHCP client. When processing raw DHCP packets, the client replaces the validated packet length with an attacker-controlled value from the IP header without re-validating the minimum size. This leads to an integer underflow when subtracting header sizes, causing a subsequent memory copy with a massively oversized length. An attacker on the same network segment can send a specially crafted packet to crash the DHCP client, resulting in denial of service and loss of network connectivity.
CVE-2026-13732 1 Redhat 9 Cost Management On Premise, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-09 7 High
A flaw was found in GDB's STABS debug format parser. The read_member_functions() function in gdb/stabsread.c contains a linked list removal bug in the code that separates destructor and non-destructor member functions of C++ classes. The bug causes the destructor entries to remain in the main function list while the list length counter is decremented, resulting in an out-of-bounds write when the function list is copied to its final allocated array. An attacker can craft an ELF binary with malicious .stab and .stabstr sections that triggers this out-of-bounds write when a user opens the file in GDB and performs any symbol-inspection operation such as setting a breakpoint. The inferior process does not need to be executed. Under controlled conditions, this was demonstrated to achieve execution of arbitrary commands within the GDB process.
CVE-2026-87876 2 Openprinting, Redhat 7 Cups, Enterprise Linux, Hardened Images and 4 more 2026-11-06 3 Low
Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations.
CVE-2026-85498 2 Polkit Project, Redhat 5 Polkit, Enterprise Linux, Hummingbird and 2 more 2026-11-06 3.5 Low
A flaw was found in polkit. When processing input that begins with a null byte, an arithmetic error in the authentication agent helper causes an integer underflow during buffer length calculation, resulting in an out-of-bounds memory read. An attacker capable of supplying crafted input can trigger this flaw, potentially causing an application crash and resulting in a Denial of Service (DoS).
CVE-2026-59849 2 Libssh, Redhat 12 Libssh, Enterprise Linux, Enterprise Linux For Els and 9 more 2026-11-06 3.1 Low
A flaw was found in libssh. Logic errors in automatic certificate-based public key authentication can cause libssh clients to loop indefinitely when configured certificates are missing or repeatedly rejected by a server, leading to denial of service.
